I think after 3.11 everyone is facing a difficulty on deciding what to believe and what not. We now start to notice how much we dependent on science and technology, and how we do not really understand those two: what they are and how they work. I came up three examples for this theme: cell phones, hazard maps, and our life lines.
Cell Phones
On 3.11, a lot of people got useful (and some not-useful) information on the Internet. And in order to connect to the Internet, people used their personal computers, laptops, and smart phones. Many ordinal cell phone were useless, because they have Internet connection but they did not work after the earthquake. It reminded us how much we depend on cell phone in order to connect with others, and it was clear that a lot of people got anxious about their phones not working properly, even in Tokyo at that night when a lot of people got stuck in there.
Tsunami hazard maps
Many local government have been providing a hazard map before 3.11. Hence people should have been prepared at least with the matter of preparation on Tsunami. However, the map turned out to be a failure this time, because it was 想定外(beyond assumption). If safe area and dangerous area were divided with clear lines, then people tend to believe that those lines are "scientifically proved" and therefore, it is right. Few people understand how those lines were estimated and how they were drawn by whom.
Liquefaction of the roads in Urayasu
There were also some maps that warn the residents about the danger of liquefaction, but they did not really represent what actually happened in the area. Addition to the map failure, the water line was broken. People in Urayasu were out of water for several weeks due to liquefaction of the land. One of my friends went Osaka till things get calmer. I cannot imagine how my family and I are going to live in a house without a water supply. We are too familiar with water coming from all the pipes by just turning the tap.
